Application filed July 21, 1914.

To all whom it may concern. v

Be it known that 1, JOHN T. SGHAAFF,

a citizen of the'United States, residing at a simple, cheap, durable and eliicient punch for perforating strips of paper or cards for any purpose whatsoever and to limit the manual labor necessary to be performed thereon to the positioning of a light part and the closing of an electric circuit. I use but twelve punches and twelve keys for operating them which are sufiicient to punch all holes without either shitting or using combinations. I also arrange the keys so that it is unnecessary to more the hand around over the key board as a slightmovement of each finger enables it to reach any key properly operated by that finger.

In the punches now in general use, the field on the card being punched and all the fields to be' punched are hidden from View. I provide an index card carrier caable of receiving a strip cut from a card of thekind being punched. The card carrier and card move along with the card be- ;ing punched, and a fixed pointer indicates the column which will be punched at the next key depression. This makes greatly for accuracy. As a further means for eliniinating error, I provide a simple rheostat and ordinarily allow only enlongh current to energize the magnet to pun'lh a single hole at one time. Hence if two keys, are depressed simultaneously the power is insulli cient to force the punches through the paper and a very fruitful source of error is eliminated.

As the operator does not have to pound the keys but simply apply a light pressure the nerves are much less disturbed than with the hand power punch. This also makes for accuracy. And the location of the keys where they are easily reached while the arm is held in a natural position is a further material help.

While I do not limit myself to the use of one magnet, one circuit and one pair of contact points, in the preferred form of my Specification of Letters Yatent,

or desirable to use more punches.

device as applied to a punch for tabulator record cards, I have not found it necessary f the drawings herewith, Figure 1 is a perspective view of tl'ie'machine. Fig. 2, is'a right to left section, through the center of the machine. Fig. 3 is a modification of the slide bar. Fig. 4, is a fore and aft sec tion on a line just to the right of the line of Fig. 5, sh as a form of escapement well suited toiny present. device. Fig. 6, shows a form of carriage skip arrangeused in some 7, shorts a top typewriting machines. Fig. plan view of the key-levers,- punch levers, push fingersand punches and Fig. 8 represents a modified form of uide and support for the left-hand end or the slide bars.

The key-levers 3, over-lie the contact "tact mechanism and when a key 3 is depressed, the contact frame 27 is carried down, rocking shaft on its slide be rs,

trunnions and through arm 29 carried by shaft 25, forces the end oi contact arm 30, against insulating block 33., carried by. contact spring 39., bringing its contact point against contact point which is) carried by a support capable of yielding slightly under pressure. Arm 8% of the motor-plate 15 overlies the tree end of arm 30, and when the inotoi-plate i5, is brought down by the magnet 16, arm 3% strikes the free end of arm 30, forcing it below e clock 31, andpermitting spring 32 to withdraw its contact point from point 33, breaking electric circuit, and thus lg the mag net 16, whereupon spring '65 raises the mo tor-plate 1510 its position of rest.

Mounted on the horizontal arm 100 of key-levers 3 are plates 4, having an inclined cam surface which engage studs 5 of slide bars 6 and when key is depressed, a barv 6 is summed toward the left, bringingits bent end 7, against the uprightarm. of push finger 8, which is pivoted at 10 to punch lever 11, which lever is -tnlcruined at 12- and overlies punches 13.

\Vhen a push finger 8 is turned toward the left on its pivot 10, it is brought under the edge of motonplate l5 and receives movement therefrom when the magnet 16, is'

dog rocker 39 with which. the link 37 is a sociated for imparting movement to the s rocker.
